Title: Lubricant composition containing mixed friction modifiers
Inventor: BLOCH RICARDO
IPC: C10M141/06
Filed: 1993-04-09
Granted: 1999-07-06
Abstract: The present invention provides an improved lubricating oil composition for autom otive internal combustion engines and transmission which comprises an oil of lubricating viscosity having admixed ther ewith a minor amount of friction modifier composition which reduces the coefficient of friction between moving mechanical parts, thereby providing for enhanced fuel economy. The friction modifier composition comprises a combination of an alkoxyl ated hydrocarbyl amine and a polyol partial ester of a saturated or unsaturated fatty acid or mixture of such esters, each prefera bly present in the range of from about 0.1 to about 1.0 % by weight based on the weight of the oil. This combination of components p rovides for synergistic fuel economy effects particularly when used as components in automotive crankcase lubricants also con taining conventional additive packages, which effects are not observed in oil which contains one or the other of these compone nts alone.

Granted: 1996-10-01
Abstract: A transmission is provided wherein selected configurational parameters of interacting spur gearing are modified to abate the vibration levels thereof due to the effects of differential thermal expansion of the gearbox housing. The chordal addenda of the gear teeth of the interacting spur gearing are extended by a predetermined amount, based upon the computed relative radial displacement of the centerlines thereof due to the differential thermal expansion effects, to provide modified interacting spur gearing having increased outside diameters. Such modified spur gearing provides an effective centerline spacing for the trans-mission such that the interacting spur gearing thereof has an operating contact ratio greater than the design contact ratio at en-gine start up. As the transmission reaches stabilized operating conditions the operating contact ratio of the modified spur gearing is substantially equal to the design contact ratio due to the effects of differential thermal expansion on the transmission gearbox housing. In addition, the helix angle of the interacting spur gearing is substantially increased to counteract the effects of differen-tial thermal expansion on the gearbox housing.

Abstract: An envelope having front and rear faces which are joined to form a pocket defined by an opening between respective upper edges of the front and rear faces.  A flap is joined to the upper edge of the front face and may be folded to overlap a portion of the rear face.  An adhesive region is provided on an inner face of the flap, with a line of weakness extending across the adhesive region. When the envelope is first used, only that portion of the adhesive region above the line of weakness is used to fix the flap to the rear face.  The addressee opens the envel-ope by tearing the flap along the line of weakness.  The opened envelope can then be reused, with that portion of the adhesive region beneath the line of weakness being used to again fix the flap to the rear face.
